An unresolved issue in the study of sentence comprehension is whether the process of gap-Wlling is mediated by the construction of empty categories (traces), or whether the parser relates Wllers directly to the associated verb’s argument structure. We conducted an eventrelated potentials (ERP) study that used the violation paradigm to examine the time course and spatial distribution of brain responses to ungrammatically Wlled gaps. The results indicate that the earliest brain response to the violation is an early left anterior negativity (eLAN). This ERP indexes an early phase of pure syntactic structure building, temporally preceding ERPs that reXect semantic integration and argument structure satisfaction. The Wnding is interpreted as evidence that gap-Wlling is mediated by structurally predicted empty categories, rather than directly by argument structure operations.
